How to Use the Hill Start Assist Function in a Car?

Method to use the hill start assist function in a car: When starting the vehicle on a steep or slippery slope, the driver switches from the brake pedal to the accelerator pedal, which may cause the vehicle to roll backward, making it difficult to start. To prevent this situation, the hill start assist control temporarily applies brakes to all four wheels to prevent the vehicle from rolling back. Working principle of the hill start assist system: When the vehicle is on an uphill slope, at the moment the foot leaves the brake pedal and moves to press the accelerator, the HAC system automatically maintains brake oil pressure for 2 to 3 seconds, preventing the vehicle from rolling back due to gravity and inertia. When the accelerator is pressed, the system gradually reduces the braking force. Once the HAC's brake control ends, the vehicle moves forward steadily as the accelerator is pressed. If the accelerator is not pressed, the HAC's automatic brake control will also end after 2 to 3 seconds.

How to Repair Car Scratches with Toothpaste?

Method for repairing car scratches with toothpaste: Use a soft cloth or sponge to apply toothpaste and gently polish the scratched area. Be careful not to apply excessive force to avoid large-scale polishing that may cause a matte finish and affect visual appearance. Toothpaste has a polishing effect and can repair some minor scratches. However, it is not recommended for car owners to use toothpaste for repairs, as improper handling may result in more severe scratches. If scratches appear on the car's paint surface, it is advisable to visit a car beauty center for polishing. The car's paint surface consists of four layers, from the inside out: the electrophoretic layer, the middle coating layer, the color paint layer, and the clear coat layer. After the car body is assembled, robots immerse the entire body in an electrophoretic pool to form the electrophoretic layer, which serves as an anti-rust barrier. The middle coating layer is the second layer of paint, which also provides anti-rust protection and enhances adhesion to the next paint layer. The third layer is the color paint layer, which displays the various car body colors visible in daily life. The fourth layer is the clear coat layer, which protects the paint and enhances its glossiness.

How to Determine the Condition of Spark Plugs?

Methods to determine the condition of spark plugs: 1. Short-circuit test: Let the engine idle, and use a screwdriver to short-circuit each spark plug one by one. Carefully listen to changes in engine speed and sound. If the changes in speed and sound are obvious, it indicates the spark plug is normal; if the changes are not obvious, it indicates the spark plug is abnormal. 2. Spark test: Unscrew the spark plug and place it on the cylinder block. Use a high-voltage wire to test for spark. If there is no spark or a weak spark, it indicates the spark plug is leaking or not working. 3. Visual inspection: Remove the spark plug and observe its appearance and color. If it is reddish-brown or rust-colored, it indicates the spark plug is normal; if it is oily, it indicates the spark plug gap is misadjusted or there is excessive fuel supply, or the high-voltage wire is short-circuited or open-circuited; if it is black as if smoked, it indicates the wrong heat range was selected for the spark plug or the mixture is too rich, or engine oil is leaking into the combustion chamber.

How to Check the Manufacturing Year of a Tire?

Method to check the manufacturing year of a tire: There is a set of 4-digit numbers on the sidewall of the tire. The first two digits indicate the week of the year, and the last two digits indicate the year. For example, "3512" means the tire was manufactured in the 35th week of 2012. The expiration date of the tire can also be found on the sidewall. Generally, the shelf life of a tire is 5 years, and when replacing a new tire, the production date should not exceed 3 years. Car tires are one of the essential components of a vehicle, as they directly contact the road surface and work together with the car's suspension to absorb shocks during driving, ensuring good ride comfort and smooth driving. They also ensure excellent adhesion between the wheels and the road, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The crucial role that tires play in automobiles is increasingly being recognized by people.

How to Check Tire Width?

Method to check tire width: The tire label is uniformly located on the tire sidewall. Taking the tire specification 195/65R15 as an example, 195 indicates that the tire width is 195mm, 65 represents the tire's section height as a percentage of the width, which is 65%, R stands for radial tire, and 15 denotes the rim diameter of the car as 15 inches. Tires are ring-shaped elastic rubber products installed on various vehicles or machinery, typically mounted on metal rims. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning performance.
